Yes, Optimism a Layer-2 network for Ethereum. It’s an optimistic rollup and is fully EVM-compatible, which means it’s very easy to port any smart contracts from Ethereum to Optimism.
Optimism is a Layer 2 netowork and is part of the larger Ethereum ecosystem. However, it’s not part of the Ethereum blockchain. Instead, Optimism uses Ethereum for security by posting summaries of its block to the Ethereum blockchain. This is increases the total throughput of the Ethereum blockchain.
